I absolutely think, this is the way, a cultural event where the "event currency" is btc-lightning. It definitely shpuldnt be labeled as Bitcoin event because it would deter nocoiners.
Then have some people nocoiners can relate to casually hanging around (like Natalie Brunell or Jack Mallers) and just chat with people..
Not sure if it would be a lightning event or an enlightenment event, if you catch my drift.
